Smash Ace
So I'm running 3.5 homebrew and booting through USB Loader GX, and occasionally, I'll ledgedrop side-b (tranquilizer) on stage and the game will lock (with that lovely cacophony of tones to boot). The most recent occasion could help: I was playing a Lv9 Samus on Smashville and did this maneuver and at the same time Samus shot a homing missile. Neither projectile made contact with anything, nor did Snake land on stage. The game froze shortly thereafter.
